Gallium ionization potential

Gallium has a beautiful silvery-blue appearance it wets glass, porcelain, and most other surfaces (except quartz, graphite, and Teflon) and forms a brilliant mirror when painted onto glass. Selected physical constants of gallium are summarized in Table 1. The atomic radius and first ionization potential of gallium are almost identical with those of almninum and the two elements frequently resemble each... 

Indium is a member of the group 13 (formerly called IllA) elements along with boron, aluminum, gallium, and thallium. In aqueous solution, only In(lll) is stable, but compounds with I + and 2+ valences have been isolated [2], The ionic radius of In in sixfold coordination is 0.81 A in eightfold coordination, 0.92 A [3]. Although indium is not a transition metal, there are many aspects of its chemistry that resemble iron. The ionization potential, ionic radii, and coordination number of In are similar to Fe.

At each optimized geometry, we used the P3 [9] and NR2 [11] electron propagator approximations to calculate the vertical ionization potentials of the molecules. For these calculations, the 6-311G(2df,2pd) basis sets [15-17] were used. Gallium d-orbitals were included and all other core orbitals were dropped in the propagator calculations.
